I see this is purely chemical. Biggest problem as I see it is not how you start the Al+NaOH reaction, but how you stop it once begun. That and disposing of the sodium aluminate waste product."
"Yes, mild steel plates. I'm afraid I don't have any data worth a damn for this beyomd 'it works ok - It was done as a feasibility study and also to assist Martin with his H-Brifge tests., and scrapped dureng the summer."
There is one possible factor which can intrude if the electrode spacing is under 3mm (1/8in) or so. If the cell is left standing for some time whiskering between plates and also the trapping of clots of iron hydroxide can mean you get…"
"What field? Technical sipport engineers work in every field imaginable. If you want to work in the hydrogen field, wait another 10 years and there may be jobs- right now it is a tiny niche area. Start thinking about qualifications in chemical…"
The problem would be that HHO systems require DC, even pulsed DC which is what a standard Pulse Width Modulator produces. The H-Bridge produces square-wave AC., so less than ideal. You could use such an AC system with blocking diodes to…"
"As you can see from the scopeshot above, Martin's method does produce a clean square wave with a very easily adjustable mark/space ration and can produce frequencies between 1-2 Hz. and at least 1000 Hz. Simple and inexpensive. "
